Constructional engineering gravel crushing device and construction method thereof

Abstract

The invention discloses a gravel crushing device for constructional engineering. The gravel crushing device comprises a box body, a feeding hopper, a crushing mechanism, a conveying barrel and a discharging hopper, the feeding hopper is arranged at the top of the box body; the crushing mechanism is arranged in the box body; the crushing mechanism comprises a first crushing roller, a second crushing roller and a first motor; the material conveying barrel is columnar, and the interior of the material conveying barrel is hollow; the material conveying barrel is horizontally mounted below the crushing mechanism; a feeding port is formed in the left side of the top of the conveying barrel, and a discharging pipe is arranged on the right side of the bottom of the conveying barrel; a screw rod is arranged in the conveying barrel in a full-length manner; a discharging opening is formed in the lower part of the discharging pipe; according to the device, the feeding hopper can be blocked when gravel is crushed, and dust drifting and gravel splashing are avoided; and through arrangement of a screw rod, unqualified sand and stones can be screened out through a filter screen, and automatic sand and stone screening after crushing can be achieved.

Description

technical field [0001] The invention belongs to the technical field of crushing devices, and in particular relates to a sandstone crushing device for construction engineering and a construction method thereof. Background technique [0002] Construction engineering refers to engineering entities formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines, and equipment. And projects that can form internal spaces to meet people's needs for production, living, learning, and public activities. [0003] Concrete is an indispensable building material in construction engineering, and a certain proportion of sand and gravel needs to be added when making concrete, and large-scale sand and gravel need to be crushed before it can be used. The dust generated during the crushing process is processed, and the sand and gravel can easily jump out of the feed port, which will not only increase the...

Problems solved by technology

[0003] Concrete is an essential building material in construction engineering, and a certain proportion of sand and gravel needs to be added when making concrete, and large-scale sand and gravel need to be crushed before it can be used. The dust generated during the crushing process is processed, and the sand and gravel can easily jump out of the feed port, which will not only increase the workload of the user's subsequent cleaning, but also pose a safety hazard. For the ground sand and gravel, in order to ensure the quality of the sand and gravel, It also needs to be screened again, increasing the process and reducing work efficiency
